Application filed July 29, 1918. Serial No. 247,349.

To all whom it may concern:

citizen of the United States, residing at Berwyn, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Liquid-Distributing Systems, of which the following is a full, clear, concise, and exact description.

This invention relates to a liquid distribting system, andmore particularly to a system and apparatus for distributing a hot viscous compound to a plurality of individual containers.

The object of this invention is to provide a system and apparatus by means of which a plurality of small individual containers may be rapidly and eiliciently filled with a hot compound which will be maintained at a desired temperature and will be free from lumps and bubbles.

In accordance with the general features ofthis invention, there is provided a liquid containing tank connected by means of suitable piping with a discharge nozzle which is provided with suitable controlling'mechanism by means of which the compound from 'the tank may be circulated through it to heat the connecting pipe and nozzle preparatory to the discharge of the liquid into the containers.

Means are also provided in the nozzle whereby, during the time that the liquid is discharging through one connecting pipe and the discharge nozzle, another pipe connected with the nozzle will he open to the air which will be drawn through it to remove all of the liquid remaining therein after the heating process.

Means, are also provided for draining" both nozzle connecting pipes when the nozzle is not'in use for filling containers.

Other features or" the invention relate to the details of construction of the nozzle and the arrangement of pipes in the supply tank for eliminating air bubbles from the nozzle and for recirculating the liquid in the tank for the purpose or" thoroughly mixing it,

In the drawings illustrating this inven-" tion:

a shown in the drawings, 5 designates a valve casing provided with a pistol gri handle 6 through which extend supply and return pipes 7 and 8 which terminate at one end in .port openings 9 and 10 leading through the wall of the valve casing 5. Located within the valve casing 5 is a cylindrical slide valve 12 provided with passages 13, 14, 15, and 16. Passages 13 and 14 are joined together within the valve 12 and are adapted in the normal position of this valve to register with the port openings 9 and 10 of the valve casing 5. in this position of the; valve 12 there will be a free passage for liquid from the supply pipe 7 through the openings 9 and 10 in the casing, the passages 13 and 14: in the valve, to the return pipe 8. The supply and return pipes 7 and 8 lead to a liquid supply tank 20 and are there connected with pumping mechanism in a manner and for the purpose hereinafter described. k

The valve 12 is slidable within the casing 5 and has one end connected with a pivotal lever adapted to be grasped by the hand of an operator to move it inwardly against the tension of a spring 26 to bring the openings 15 and 16 of said valve into registering relation with the port openings 9 and 10 through the casing 5. As shown in the drawings, and particularly in dotted lines in Fig. 2. the passage 15 leads out to the right-hand end of the slide valve 12 and thence through a passage 27 in the discharge end of the valve mechanism. The other passage lfiopens through the'upper surface of the slide valve 12 and is adapted, when this valve is moved, to bring the passages 15and 16 into a registeringrelation with the passages 9 and 10, to register with an air inlet passage 28 through the upper part of .the valve casing 5.

The valve member 12 may be locked in its operated position by means of a hook member 30-pivotally supportedv upon the outside of the casing 5 and adapted to engage an extending pin 31 carried by, the inner end of the valve member 12 and operating ina slot 32 through the casing member 5. This locking mechanism is used when it is desired to drain the liquid from the piping and valve during the time that it is not in use. This feature will be further described in connection with the description of the operation of the apparatus and system.

The left end of the spring 26 bears against a plate or washer 35 carried by a screw threaded stud 36 which extends through a removable cap 37 mounted upon the left end of the valve casing 5.

In the operation of the apparatus and system of this invention it is desirable that the piping and nozzle be first heated to approximately the temperature of the liquid compound before the liquid vcompound is supplied to the containers. This may be accomplished by setting the slide 12 in its normal position and operating pumps 40 and 41 located in the container 20. As these pumps operate, liquid will be drawn into a pipe 43 by the pump 41 and will be forced through a pipe 44, a four-way steam valve 45, pipe 46, the supply pipe 7, through the port opening 9 of the valve mechanism,

passages 13 and 14 of the valve, opening 10, and through the return pipe 8 to pipe 47' through the pump 40 and a pipe 48 back into the container. Since the liquid in this container is also maintained at the temperature at which it is to be used, its circulation through they pipes 7 and 8 and the valve mechanism, as hereinbefore described,

will bring the temperature of these pipes and the valve mechanism up to approximately the temperature of the liquid, thereby preventing the liquid from being discharged ina lumpy or otherwise unsatisfactory condition.

After the pipes 7 and 8 and the discharge nozzle have been heated to the required temperature the valve 12 will be moved backward into its operating position to bring the passages 15 and 16 into registering relation with the port openings 9 and 10, whereby liquid will be discharged from the tank through the opening 27 of the nozzle mechanism into suitable containers. In this position of the parts liquid will be drawn from the tank 20 through the pipe 43, the pump 41, which will force it through the pipe 44, the four-way steam valve 45, the pipe 46, the discharge plpe 7, the port opening 9 in the casing 5, and the passage 15 in the valve 12 to the discharge passage 27. At the sametime the pump 40 will by its action draw air through the valve casing 5 at the opening 28, through the passage 16 in the valve, through the port opening 10 in the casing 5, the return pipe 8, pipe 47 and through the pump 40 and pipe 48 which opens downwardly into the tank 20. This action of the pump 40 will clear all remaining liquid from the pipe 8 and prevent air from getting into the pipe 7 or the discharge passage 27 of the nozzle mechanism. \Vhen the filling operation has been completed it is desirable to drain both pipes 7 and 8 of the compound in order to prevent it freezing in these pipes and thereby interfering with the circulation of the compound from the tank when the apparatus is again put into use. To accompllsh this the valve 12 is locked in its operating position by means of the hook 30 and pin 31 and is then suspended by means of a hook 50 provided on the casing 5. The four-way steam valve 45 is then turned to the position shown in dotted lines in Fig. 8, whereby the pump 40 will, by its suction, draw air through the openings 27 and 28, the passages 15 and 16, the pipes 7 and 8, and through pipes 46, 47, and 51. All liquid remaining in the nozzle and pipes at the completion of the filling operation will therefore be withdrawn from these pipes back through the pump 40 and discharged into the tank through the pipe 48.

The pressure at which the liquid is circulated through the discharge pipe 7 by the pump 41 may be regulated by means of a valve 56 connected with the pipe 44 and controlled by means of a handle 57 above the container 20. The opening of this valve will provide a by-path for the liquid from the pipe 44 and the amount of its opening will determine the amount of pressure upon the liquid which passes through the pipes 46 and 47.
